We look at the division of 86107297 by 260 
The aim is to understand the frequency of 260 in 86107297.

Going ahead to step 1:
260 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 260

Moving on to step 2:
260 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 260

Advancing to step 3:
260 goes into 861 3 times with a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 780 from 861, we get 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 260

Let's proceed to step 4:
260 can be fit into 810 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 780 from 810 and we're left with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 260

Advancing to step 5:
260 goes into 307 1 times with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 331.0
Subtracting 260 from 307 leaves us with 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 260

Advancing to step 6:
The number 260 fits into 472 1 times, leaving a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 3311.0
Subtract 260 from 472 to get 212.
Bring next digit (9) of the dividend behind the 212 and repeat the process: 2129 / 260

Let's proceed to step 7:
260 goes into 2129 8 times with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 33118.0
If we take 2080 away from 2129, we end up with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 260

On to step 8:
260 can be fit into 497 1 times, resulting in a remainder of 237.
The next digit of our result is 1. 
Result so far: 331181.0
Subtract 260 from 497 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 9:
When dividing 2370 by 260, we get 9 with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 331181.9
If we subtract 2340 from 2370, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 260 fits into 300 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 331181.91
Subtract 260 from 300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 260 is 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 331181.911
Deduct 260 from 400 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 331181.911, and the remainder is 0.014.
